Established in 1686 by Henri de Tonti, a lieutenant of La Salle, this trading post near the mouth of the Arkansas River was the first successful French settlement in the Lower Mississippi Valley. Apparently abandoned and later reclaimed by the French in the 18th century, Arkansas Post went on to serve the Spanish and, later, the Territory of Arkansas. Its position on the river necessitated frequent changes of location; this is the post's final location.
